Answer:
(1) 23.55mm³
(2) 340.17in³
Explanation:
Volume of a cone is:

'r' - radius
'h' - height
Cone 1:
The height of Cone 1 is 10 mm. The Diameter of Cone 1 is 3mm.
Radius is half the Diameter.

The radius is 1.5 mm.

The volume of Cone 1 should be about 23.55mm³.
Cone 2:
The height of Cone 2 is 13 in. The Radius of Cone 2 is 5 in.
Using 3.14 as pi:

340.166666667 ≈ 340.17
The volume of Cone 2 should be about 340.17in³.
